After some time working for Vurrha Chur's organization, Agar had become a more ambitious individual and began acquiring wealth and favors from individuals who bribed her to leave them alone when she was assigned to come after them. She carefully built up her strength and kept individuals alive who she believed might become useful later. During her time working for Vurrha Chur, he considered her his top enforcer. She kept apart from the rest of Chur's employees, including Sevv Sunb, the Quarren crime lord's book keeper, who Agar disliked. While working for Chur, Agar slowly prepared for departing Vurrha's organization.[1]

Ereen Agar stood 1.8 meters tall with light grayeyes, tan-colored skin, and brown hair, which she usually kept long and pulled back. Like most Zabraks, Agar had facial tattoos, which were thin, dark lines with a swirled pattern. In her work as a guard for a shipping company, Agar did not care whether she had to go up against pirates or law enforcement. Due to the influence of Vurrha Chur, Agar became more ambitious and willing to wait patiently for the long-term, although she was still annoyed by smaller setbacks. She was able to carefully control her emotions, but would show pleasure in causing violence in order to frighten her opponents. She enjoyed encountering challenging opponents and fought even more skillfully than usual in dangerous situations. Despite her preference for violence, Agar did not attack individuals without a purpose, since she saw that as a waste.[1]

Although she was careful and efficient, Ereen Agar would accept bribes and favors if she believed that it would help her in the long run. She wanted to gain enough riches and favors to prepare for her departure from Vurrha's Blood, but she patiently to gain further strength despite her dislike and indifference towards the rest of Vurrha's employees, including Sevv Sunb, Chur's book keeper. Agar's attitude towards Sunb made him dislike her, and led him to believe that she despised him for his lack of fighting skills. Although she spoke quietly, Agar was excellent at intimidating her opponents, and was experienced in surviving in rough places. Ereen Agar spoke and was literate in both Galactic Basic Standard and the Zabrak language.[1]

A Force-sensitive, Ereen Agar was largely untrained in using the Force, but she did follow her instincts and use the Force to enhance her physical abilities. She was skilled in combat with blaster pistols, blaster rifles, and heavy weaponry. She was also skilled in the use of melee weapons, including vibro weapons. In melee combat, Agar was extremely quick, and sometimes used the Force to give herself an edge. Although she did not regularly use armor, she was trained in how to use it. She was a capable pilot and was also somewhat skilled at treating wounds.[1]

While working for Vurrha's Blood, Ereen Agar owned a heavy blaster pistol and a vibroblade, both of which she wore openly. The heavy blaster and vibroblade had each been customized to be more deadly in combat. She also carried a grappling spike launcher, a medical kit, and a utility belt. In the belt, she stored a medpac, a tool kit, a glowrod, a comlink, and some emergency food capsules, as well as a spare power pack and energy cell to power her weapons. In order to fight more effectively in melee combat, Agar preferred wearing snug shirts along with loosely fitting jackets and pants that allowed her to move quickly and easily. For transportation, she owned a customized speeder bike that was modified to fly at greater speeds than a standard Ikas-Adno22-B Nightfalcon speeder bike. At most times, Ereen Agar carried around eleven hundred credits on her person.[1]
